OIL-FEED FOR LAMPS.

$PECIFICATION forming part of Letters Patent No. 395,460, dated January 1, 1889.

Application filed March 30, 1888. Serial No. 268,974. (No model.)

To aZZ 10710722 it may concern.-

Be it known that I, CHRISTIAN SIEcIIoLD, of Salinas, in the county of Monterey and State of California, haw'c invented a new and Improved Oil-Feed for llamps, of which the following is a specification, reference being had to the annexed drawings, forming apart thereof, in which Figure l. is a side elevation of my improved oil-feed for lamps, and Fig. 2 is an enlarged vertical section of one of the lamps.

Similar letters of reference indicate corresponding parts in both views.

The object of my invention is to provide a simple and effectual device for uniformly sup plying lamps with oil.

My invention consists in a lamp provided with a valve in the bottom thereof connected with a float contained by the body of the lamp and a pipe leading from the valve-opening to an oil-reservoir, all as hereinafter more fully described.

The lamp-bodyA is provided with a burner, B, of the usual description. The bottom 0 of the lamp is provided with a central aperture, (1, furnished with the downwardly-projecting tube Z). \Vithin the lamp is placed an annular float, D, of cork or other light material, which is connected by the yoke c and tube cl with the mercurial valx e E, which is adapted to close the end of the tube 1'). The mercurial valve E consists of a cup, f, attached to the lower end of the tube (Z and partly filled with mercury. The cup f, when carried upwardly by the float D, brings the mercury into contact with the lower end of the tube 1), and thus closes the tube, so that no oil can pass. In the tube cl is formed an aperture, g, through which oil passes to the lamp. The valve and tube 1) are inclosed in a chamber, F, formed 011 the bottom of the lamp, and the said chamber F communicates by a pipe, G, with the supply-pipe H. In the pipe G is a valve, e, for shutting off the flow of oil to the lamp.

The supply-pipe H con'n'nunicates with an oil-reservoir, I, arranged above the level of the lamps. Any desired number of lamps may be connected with the pipe H, and the supply.

of oil to the pipe H is regulated by the valve J.

hen the oil in any one of the lamps is at its normal level, the float D is borne upward, holding the mercury in the cup f against the end of the tube 1); but when the oil burns away, so as to reduce its level, the float and the valve drop by their own gravity, and oil enters the lamp through the opening 9 until the oil in the lamp reaches the normal level, when the float D again presses the valve E, thereby shutting off the oil-supply to that lamp.

Having thus described my invention, I 012 im as new and desire to secure by Letters Patent 1. The combination, with the lamp body or vessel A, having an inlet in its bottom, of the float D Within the body, a depending tube, d, extending down through the said inlet, and having an opening, g, through one side and a cup on its lower closed end, substantially as set forth.

2. The combination, with a lamp-body, A, having a depending tube, 2), of a float, D, within the body, a pipe, (I, closed at its lower end, suspended from the float, passing down through the tube 1), and provided in its side with an opening, g, said opening being below the lower end of the tube b when the float is lowered, substantially as set forth.

CHRISTIAN SIEGHOLD.
